Laser sails use thin multi-square-kilometer sails (often several hundreds of kilometres in diameter) made of ultra-light reflective material. These are propelled by visible-light lasers with up to thousands of terawatts of power, allowing a reasonable rate of acceleration with no on-board reaction mass. Generally used for unmanned craft.
The Starwisp, the first successful interstellar probe to any destination, reached Alpha Centauri in 202 AT
Maser sails use microwave laser beams, or masers, for propulsion, and consist of a thin mesh capable of interacting with the longer wavelength of these beams. Many early interstellar probes used maser sails, sometimes including an extra reflective element to allow deceleration. Even in the current era lightweight maser-sail probes are sometimes used for exploration purposes.
Solar Surfing - Text by James Ramsey Solar surfing, also known as sun diving or sun skipping, is a form of vec entertainment in which specially designed ships are placed in a orbit such that they will fly through the outer edges of a star and even skip across its surface. Highly dangerous sport requiring high speeds and extremely accurate trajectories. May also refer to riding solar flares and other solar eruptions.
